+# **💥 BREAKING CHANGES**
+
+## Workflow Metadata **(Public Preview)**
+
+The built in  `__temporal_workflow_metadata`  query now uses `io.temporal.common.converter.RawValue`  for the return type. This should help address issues where users data converters could not properly convert the `WorkflowMetadata` protobuf type. If you are using a custom data converter that does not support `RawValue`  you will need to update it to support this type.
+
+Note: The built in Temporal `DefaultDataConverter` already supports `RawValue`  and does not require any changes.
+
+## Nexus
+
+When an `ApplicationFailure` is returned from a Nexus operation handler the SDK will now translate it into an `INTERNAL` non-retryable error. Previously it was translated to a `BAD_REQUEST` error. This is to align with the behavior of Nexus operations in other SDKs.
+
+# **Highlights**
+
+### Nexus Operation Cancellation Types (Pre-release)
+
+Users can now specify the cancellation type when cancelling a Nexus operations from a workflow. This allows for more granular control over how Nexus operations are cancelled, and how the caller is notified of the cancellation.
+
+### Springboot (Pre-release)
+
+Temporal Java SDK Springboot integration now automatically registers Temporal interceptors. Interceptors will be registered in the order specified by the `@Order` annotation.
+
+### Automatic Poller Scaling (Pre-release)
+
+Users can now configure Workers to automatically scale the number of concurrent polls they make. To enable use `setWorkflowTaskPollersBehavior`, `setNexusTaskPollersBehavior`, and `setActivityTaskPollersBehavior` arguments of the `WorkerOptions.Builder` constructor to `PollerBehaviorAutoscaling`. You can expect fewer unnecessary polls during low load, and increased polls during high load when they can be used to increase task throughput.
